0=16x^2+48.6x+37.5
We move all terms to the left:
0-(16x^2+48.6x+37.5)=0
We add all the numbers together, and all the variables
-(16x^2+48.6x+37.5)=0
We get rid of parentheses
-16x^2-48.6x-37.5=0
a = -16; b = -48.6; c = -37.5;
Δ = b2-4ac
Δ = -48.62-4·(-16)·(-37.5)
Δ = -38.04
Delta is less than zero, so there is no solution for the equation
